IMPROVED CAR-COUPLING.

W The Schedule referred to in these Letters Patent and part of the same.

To all whom it may toncern:

Be it known that I, WILLARD E. BUSH, of Damascus, in the county ofVVayne,and State of Pennsylvania, have invented a new and improvedAutomatic Car- Ooupling; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable thoseskilled in the art to make and use the same,- reference being had to theaccompanying drawings, forming part of this specification. i Theintention relates to an improvement in the couplinguscd for unitingraile'Jad-cars, whereby they are rendered more secure, and less liableto get out of order than those of ordinar construction, the improvementsbeing more particularly designed to apply to a car-coupling for which Inow have an application for a patent pending. v

And the invention consists in attaching spring-catches to thecouplingepin, to prevent its displacement by the. motionof the cars, andin the formation of the ends of the coupling-link, and in the provisionmade for bolding the link in place. 7

Figure l is an outside longitudinal view \of a drawhead, showing thelinkand coupling-pinin place, and the spring-catches attached to thepin.

Figure 2 is a vertical section of fig. 1, showing my' improvement.

Similar letters of reference indicate corresponding parts.'

A is the draw-head.

B isthe coupling-link.

G is the coupling-pin.

, To the upper end .of the-coupling pin there are attached two springs,d d, by rivets or otherwise, as seen at e. v These springs haveshoulders formed on them, .liiarked f. p I

In the pin-hole throng the draw-head, there is a recess, 9, with aprojecting lip,- h, underwhich lip the M shoulders f catch, as'the pinis inserted.

As the pin is pushed down, the springs are compressed bythe hole. abovethe recess or lip h, but when the shoulders f hays passed below the lip,the springs expand, and the shoulderscatch under the lip, as seen in fi2.

If? this position the pin is effectually prevented from jumping out bythe motion of the cars, consequently there is no danger of the carsuncoupling when in motion.

J is the spring-bar in the draw-head, against which the coupling-pinimpinges when the-cars are coupled.

The end of this bar is serrated horizontally, as seen in the drawing, at'i, and the ends of the link are hav elled 011', so as to fit theangular grooves in the end of the bar, I

By these grooves and the bevelled ends of the link, and by the pressureof the spring-bar against the end of the link, the link is held in ahorizontal position at all times, while it will accommodate itself toany difcranes in the height'of the cars in coupling.

By this arrangement the link cannot drop, but will always be ready forcoupling with another car without aid from any attendant.

-I do not claim the construction .of the draw-head in this applicationas a novelty.

What I do claim, and'desire to secure by Letters Patent, isr The springsd (l, with their shoulders, ff, and the lip 71, on the'draw-head,substantially as and for the purposeshercin shown and described, incombination with a draw-head of a car-coupling.

The above specification of my invention signed by me, this 3d day ofMay, 1868.
